Hi,
Main,java has a start button that run startActivity(new Intent(main.this,
CobaGesture.class));
CobaGesture.java has a back button that run finish();
*startActivity(new Intent(CobaGesture.this, main.class)); // No need of
this, it is creating one more instance of main Activity in stack.*
*
*
*So remove this line.*
*
*
*other hand check out either are you doing some on other operation on
button click listener or only calling CobaGesture Activity?*
*if you are calling only CobaGestureActivity then it will work fine.*
*
*
*Regards*
*Imran Ali*
